Cardiovascular Exercise: Article Analysis

Blood vessel length, when increased causes more friction or resistance thus making it more difficult for blood to flow through the vessel. In summation, increasing blood vessel length inversely effects flow rate but decreasing flow rate. My prediction was that an increase in blood vessel length would inversely effect blood flow. As evidenced in this experiment, with the increase of the blood vessel length, there was a decrease in blood flow.

Hello Dr. Hultgren! Thank you for pointing out that my research question represents a longitudinal study. I mentioned in my initial post that a mixed methods research would be better, but I only presented a quantitative question. You made great suggestions of what to consider when asking a qualitative question for this particular study. Perhaps a sound qualitative question to inquire is: In adults 18 years and older who are consuming polyphenols, does ingestion of various types of these compounds give them better energy and performance levels compared to just consuming one particular polyphenol-rich dietary source (for example grapes over cocoa) right after ingesting it? Thank you

This allows your cardiovascular centres in your brain a little bit more latitude as far as controlling your heart rate. If you were to remove a beating heart from someone's body you would find that the heart is no longer being suppressed by the parasympathetic nervous system and it will accelerate to the same pace as the sinoatrial node. The SA node generates action potentials approximately 100 times per minute due to the physiology of the heart, its own permeability to sodium and calcium via its channels, and a host of other things. Anywhere between 80 to 100 beats per minute is normal for the SA node.

Since aerobics is done while listening to music, the whole workout will actually be a fun one. It will also improve your well being, and it will make you feel a more optimistic person, which means that the quality of your life will improve very much. Therefore, if you want to have a healthy heart, you should definitely go for aerobics.

Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently.

Investigating the Effect of Exercise on Pulse Rate Aim: To see what happens to the pulse rate during exercise. Prediction: I predict that the pulse rate will increase in order to take more oxygen for respiration. The heartbeat will increase and become stronger to transport oxygen and carbon dioxide to and from the muscle cells. The breathing rate will increase in order to get rid of the extra waste such as Carbon dioxide. Respiration is the release of energy.

The method used for the study was quantitative, this was chosen rather than a qualitative as this deals with facts and figures and is an investigatory type of study. This can be either experimental or non experiment. Experimental is the method used in this study which looks at cause and effect, and involves dependent and independent variables. (Balnaves and Caputi, 2001) A qualitative study can be described as interpretive which deals with personal thoughts and feelings (Flick, 2009).

Obesity rates have continued to raise over the years. In America 1 out of 3 adults were considered to be obese. Due to these statistics obesity has become a huge concern for our country. Factors that are related to obesity are heart diseases, health issues, diabetes, and hypertension. To not be another statistic we must have a healthy nutrition and have physical activities in our daily routines. Aerobics is a great way to start a healthy lifestyle. As said in myDr, "Regular aerobic exercise improves your cardiovascular fitness by increasing your capacity to use oxygen. It does this by increasing your heart’s capacity to send blood (and hence oxygen) to the muscles." Cardiovascular exercise is extremely important because reduces health problems, improved bone and muscle health, and controls your weight.

Introduction: Exercise is a physical activity or particular movement that is used in order to become healthier and stronger. (1) Exercise, in all of its forms, has various effects on the different systems in the human body. One of the main benefits is cardiovascular health, including circulation and heart health. Exercise uses a lot of energy, which the cells derive from oxidising glucose. Meaning that the heart has to work harder to pump more blood throughout the body and the heart has to beat faster in order to achieve a high effort. (2) The heart benefits from exercise include being able to pump more blood through the body and continue working at a higher level with less strain. (3)

INTRODUCTION: High-Intensity Interval Training (HIIT) is known as one method to treat Cardiovascular Diseases (CD), such as Coronary Arterial Disease (CAD) and Heart Failure (HF), due to its potential to improve cardio respiratory fitness (1, 15). This exercise format is characterized as aerobic exercise performed in a high intensity - usually controlled by either maximum oxygen uptake or maximum heart rate – with active and low intensity. Performing exercise in high intensities mixed with active rest allows patients to tolerate a higher effort before they become tired. Heart failure patients present a diminished exercise capacity, due to a smaller Ejection Fraction (EF), which tells us how well the heart pumps blood to body. To these patients, High-Intensity Interval Training has been reported for improving Systolic Function due to the increased effort in which the heart is working (16). The necessity to provide nutrients through circulation during exercise leads to an increased contractility and consequently LV Remodeling (15). Coronary Arterial Disease Patients have a decreased blood flow to the myocardial tissue due to an obstruction inside the coronary arteries. HIIT increases the arteriovenous O2 difference, which means there is an elevated consumption of oxygen by the tissues as result of a higher stroke volume. All those benefits have been shown in the literature, but most of the studies present data with short-term interventions. A few studies discuss the benefits

A person's cardiovascular system is a very important part of fitness and one's overall health. Here are a few of the best exercises; walking running, cycling, rowing, swimming. Research suggests at least 150 minutes per week, a minimum of 30 minutes per day, five times a day a week. A few exercises that are best are, climbing, playing sports, and running is also some of the most common and affordable. At least 25 minutes of vigorous aerobic activity at least or a combination of moderate and aerobic activity are some of the best options to benefit your cardiovascular system.

Physical activity has been proven to have phenomenal benefits on the human body and is an important part of a balanced lifestyle. Statistics have shown that regular exercise can prevent illness and lower one’s likelihood of being diagnosed with a series of diseases significantly. It has been ‘medically proven’ that regular exercise can reduce a subject’s chance of being diagnosed with coronary heart disease or stroke by 35%, type two diabetes by 50%, colon cancer by 50%, breast cancer by 20%, early death by 30%, osteoarthritis by 83% and a number of other life threatening illnesses. Regular exercise can improve a person’s overall wellbeing and immunity to common illnesses. During physical activity, a person’s heart rate can increase significantly and allow more oxygenated blood to be supplied to muscles. A person’s breathing rate can increase during exercise and supply more oxygen to the lungs. The increased blood flow during exercise allows the brain to function better. Exercise has many benefits to the human body and is a major factor of disease

The benefits of physical exercise in humans far outweighs the harmful effects associated with exercise. A prescription of physical activity has been known to delay the onset or prevention of many chronic diseases. An improvement in heart function, lower blood pressure and improve functional capacity is noticed after just a few weeks of exercising. Physical activity will also result in an increase of lean muscle mass, promote weight maintenance, increased flexibility, and a generally stronger more fit individual. Conversely, exercise when preformed strenuously or obsessively can counteract such positive effects, bringing up some issues like oxidative stresses, injuries, and

There are many benefits of cardio fitness, the main advantages are; improved heart health, increased metabolism, improved hormonal/ mental health, and helps manage or ease the chances of diabetes. Your heart is a muscle, and in order for it to gain strength it needs to be worked, by getting the heart pumping at a faster rate than usual it will become stronger, larger and healthier. Cardio exercise uses lots of energy from cells to keep working your muscles. When burning calories you change from a resting level of metabolism (normal) to an exercising rate of metabolism. By doing cardio exercise for 20 minutes each session, you increase the level of your metabolism. Cardio exercise changes the hormonal profile in the body on a large scale. Exercises release hormones within the brain and nervous system, called endorphins. These hormones lessen the symptoms of depression, stress disorders and fatigue. Cardio exercise helps diabetes sufferers manage the condition. By exercising the ability to utilize glucose will increase and will help control blood sugar levels, and lessen the chances of blood sugar swings. It lowers the chances of getting type two diabetes by maintaining blood glucose and blood pressure levels at

The muscles demand more energy and oxygen due to the increased workload that comes from exercise. This causes the heart rate and respiratory rate to increase in order to provide the required additional fuel to the muscles. In addition, the entire circulatory system works more efficiently due to vascular dilation and cholesterol reduction. By improving the condition of your cardiovascular fitness you are also helping yourself live longer, decrease the risk of heart disease, lower blood pressure, strengthen your cardiovascular system, and the list goes on. These reasons alone could save you from having heart disease.
